fill out the information for the following function

Question

f(x)=cos(pi/4(x+pi/6))-3

phase shift:

vertical shift:

amplitude:

period:

*please note i did not have the pi symbol so I had to write it*

Answer 1

f(x) = A sin (B(x + C) + D

amplitude: A

period: 2π / B

phase shift: C (positive to left)

vertical: D

Use this for cosine also.
